As for the network, it's as easy. It creates a hash of a retina on a single device with no further confirmation or verification.

So al this comes down to several rather simple steps:

- if the algorithm for the hash is known, generate new hashes programmatically

- if not, but the hash is simple, reverse engineer/brute force the hash, generate new hashes programmatically

- if not, generate synthetic retina images and feed them to the algorithm

--- cut off point, and a really don't think you would need anything beyond this point for a shitty cryptocoin like worldcoin ---

- if the algorithm can differentiate between flat images and "actual" retinas, for some definition of "actual", iterate through artificial eyes until they trigger the required response
